Just a polite reminder that
Just a polite reminder that the plural of most English nouns is indicated by adding an 's' to the word, such as, "Leafs."
In this article, the author has added an apostrophe before the 's' as well, resulting in "Leaf's" as the plural form. But the construction "Leaf's" indicates the possessive rather than the plural form, suggesting a property or feature of the Leaf, as in, "the Leaf's range varies..."
One pointed, and commonly misunderstood, exception to the rule is the construction of the possessive form of the pronoun "it." The general rule is the exact opposite of the rule in this special case: the proper possessive of "it" is "its" without an apostrophe, in order to distinguish it from the contraction of the phrase "it is." Thus, "it's not always understood that the possesive form of 'it' should be spelled 'its'."
Published text always has more credibility when it adheres to correct and accepted grammar, spelling, punctuation and usage.
Again, just a courteous reminder.
